Was It Viewed? is a simple webapp that creates trackable links to you can find out if any URL has been viewed. If you sent in an online resume, asked someone to check out a video, or want to know if a friend downloaded a file, it'll let you create a simple, trackable link that'll let you know when someone is checking it out.

It doesn't matter what the link is—you just enter it into the the webapp's form, add your email address (for notification purposes), and any notes you want to add. This will provide you with a long and short URL that you can send to anybody. The downside is that the URL identifies itself as a Was It Viewed? link so the person is going to know their activity is being tracked. That said, you could always just shorten it yourself with a service like bit.ly. The creators may even add integrated support for this in the future. This definitely a specialized tool, but a good way to figure out if what you sent was ignored or not—something that can definitely come in handy during application processes.
